Cyberbullying is a virtual form (e.g., textual or image) of bullying or harassment, also known as online bullying. Cyberbullying detection is a pressing need in today’s world, as the prevalence of cyberbullying is continually growing, resulting in mental health issues. Conventional machine learning models were previously used to identify cyberbullying. However, current research demonstrates that deep learning surpasses traditional machine learning algorithms in identifying cyberbullying for several reasons, including handling extensive data, efficiently classifying text and images, extracting features automatically through hidden layers, and many others. This paper reviews the existing surveys and identifies the gaps in those studies. We also present a deep-learning-based defense ecosystem for cyberbullying detection, including data representation techniques and dif...

It provides natural systems' ability to deliver natural resources and ecosystem services. Sustainable development is crucial for the economy and society. Artificial intelligence (AI) has attracted increasing attention in recent years, with the potential to influence many domains positively. AI is a commonly employed component in the quest for long-term sustainability. In this study, we explore the impact of AI on three pillars of sustainable development: society, environment, and economy, as well as numerous case studies from which we may deduce the impact of AI in a variety of areas, i.e., agriculture, classifying waste, smart water management, and Heating, Ventilation, and Air Conditioning (HVAC) systems. Furthermore, we present AI-based strategies for achieving Sustainable Development Goals (SDGs), which are effective for developing countries like Bangladesh. The framework that we propose may reduce the negative impact of AI and promote the proactiveness of this technology.

This study used a panel data set comprising all 30 listed banks with 250 bank-year observations for the period 2013–2017. It employed the random-effects GLS regression model with cluster robust standard error and AR (1) disturbance to examine the effect of several audit committee attributes on NPLs. We found that holding audit committee meetings frequently and a higher number of independent members in the audit committee facilitate to reduce NPLs. We, however, find no explicit evidence that the other attributes of the audit committee examined (audit committee size, financial experience and financial literacy of the audit committee members, professional qualifications of the audit committee Chairman) contribute in reducing NPLs. The findings will be useful for policymakers of the banking sector in Bangladesh and the relevant regulatory ...

The purpose of the study is to scrutinize how, and to what level, the indicators of credit risk influence the profitability of commercial banks in Bangladesh. Using quantile regression analysis, this study examined a panel dataset for 22 sample commercial banks during the years 2008 to 2017. The results show that Loan Loss Provision to NPL ratio and Cost per Loan ratio were found to have a significant positive impact on Return on Assets (ROA), while Capital Adequacy ratio and Leverage ratio have a significant negative impact on the performance of banks. However, Non-Performing Loan ratio, Loan Loss Provision to Total Asset, Loan Loss Provision to Total Loan, Total Loan to Total Asset, and Log of Total Asset and Deposit, were found to have an insignificant impact on the profitability. The findings of the study assert that credit risk has a noteworthy negative impact on profitability. The study recommends that bank management should be more strategic in credit risk assessment, to curtail the exposure to credit risk and to boost profitability.

Piper diagram showed that the water quality of both sources represents Ca-Mg-HCO 3 hydrochemical facies in which the equal dominance of alkaline earth metals and weak acids was observed. According to the water quality index (WQI) ratings, 95% of the groundwater samples were found in the 'unsuitable' category for drinking, while 18% of the surface and 25% of the groundwater samples identified as 'suitable' for irrigation usages. Heavy metals present in surface water varied from 'low' to 'high' class, and the mobility of metals in 22.7% samples was comparatively high in the aqueous phase. The calculated results of the heavy metal pollution index (HMPI), heavy metal evaluation index (HMEI), and environmental water quality index (EWQI) also showed almost similar trends with the WQI. The results revealed that surface water possessed more potential non-carcinogenic harmful health risks to the residents of the study area to compare to groundwater. As regards carcinogenic health risks, on average there is a possibility of 5 persons in every 10 6 developing cancer due to lifetime exposure to Cd through ingestion of groundwater. The study concluded that long term use of poor quality water may pose a hazard to human health, crops, and soils, and therefore require to be treated before using those waters for drinking and irrigation purposes.

The study revealed that 18, 14 and 6 samples were unsuitable for irrigation in respect of HCO 3 , K and BO 3 contents in water, respectively. Among the heavy metals, the concentration of Pb, Mn, Cd and Cu in water were comparatively higher than the standard limits, which makes 22, 14, 10 and 3 samples problematic for long term irrigation in the study area. Electrical conductivity (EC) and sodium adsorption ratio (SAR) reflected that surface water samples were low to very high salinity (C1-C4) and low alkalinity (S1) hazards classes. As regards to hardness, out of 22 water samples, 2 were very hard, 8 were hard, 11 were moderately hard and only one was soft in quality. The study results concluded that HCO 3 , BO 3 , K, Pb, Mn, Cd and Cu were the major contaminants in the surface water of Sadar upazila of Jamalpur district, Bangladesh. Finally, the study suggested that the surface water in this area needs to treat to minimize the amount of contaminants before use for irrigation.

Total 20 groundwater samples were collected from the whole area and analysed for various physicochemical parameters following standard protocols at the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during March to December 2017. Concentrations of different heavy metal (Fe, Mn, Cu, Pb, Cr, Cd and Zn) in groundwater samples were measured by an atomic absorption spectrophotometer (AAS). Major cation chemistry showed their dominance in order of Ca > Mg > Na > K. Among the anions, HCO3 was the most dominating ion, which makes all groundwater unsuitable for irrigation. But considering major cations and anions, all groundwater samples were rated as suitable for drinking. In context of heavy metals, the amounts of Mn, Cd and Pb in groundwater were comparatively higher than the standa...

This trend continues to military applications too by introducing internet of military things (IoMT). Due to being at infancy level, new technologies require to move forward and assist IoMT to gain maturity. Mixed reality (MR) can be a potential technology which fuses the virtual and actual world. MR can improve the quality of service (QoS) in terms of inventory management, remote mission handling, battlefield assistance, etc. However, data among these applications is surrounded by cyber threats (e.g., illegal data modification, unauthorised data access). Blockchain is another promising technology which brings security in the distributed world. A content sharing scheme for MR application is proposed on the top of blockchain to bring security in the multi-user environment in IoMT. A smart contract is employed to manage security in accessing data by different users. Moreover, an experimental environment is set to observe the performance of the proposed scheme. The analysis manifests that proposed scheme maintains security without affecting the regular performance.

The study highlights the noteworthy knowledge gaps that will support human resource management practitioners to embed in the research towards sectoral context. Pertinent articles were selected through key search points. The Boolean logic (e.g., AND or OR) was applied to identify the relationship between search points and excerpt-related literature. The key search points covered the topic related to different terms of engagement for example "employee engagement" OR "work engagement" OR "job engagement" OR "organization engagement" OR "staff engagement" OR "personnel engagement" which were steered in diverse context particularly financial sector. Through critically reviewing the literature for the last 11 years i.e., 2009-2019, we discovered 91 empirical studies in financial sector. From these studies, we found the overall concept of engagement and its different determinants (e.g., organizational factors, individual factors, job factors) as well as its various outcomes (e.g., employee outcomes, organizational outcomes). We also formulated a conceptual model to expand the body of knowledge in the area of employee engagement for a better understanding of its predictors and outcomes. Besides, limitations of the study and future recommendations are also contemplated.
